I live in the Pacific Northwest and the dark, dreary winters have really taken their toll on me in the past. I was researching what I could do about it and learned about vitamin D deficiency and its effects. I thought why not supplement with Vitamin D and see what happens. I read that Vitamin D3 Cholecalciferol was most efficacious for supplementation so I ordered Bluebonnet's product and have been exceptionally well pleased. This is the second winter that I have taken it and I've noticed a tremendous difference in my outlook. I would recommend this for anyone living in a northern climate.
Also, last winter iHerb shipped me a bottle that was damaged during shipment. They replaced the product at no charge. I highly recommend doing business with them.

I find this D3 to be perfect for me. The D3 from lanolin sources made
my skin itchy. Bluebonnet doesn't do that. I'm pleased to have found
a lanolin free D3. I absolutely will purchase this product again and have shared the information about this product with many people who have had lanolin sensitivities to other D3 brands.

I am allergic to sheep's wool, which most D3 is derived from and cannot tolerate the brands made from it. I break out in a rash.
So far this is my first purchase of the fish oil D and I seem to be able to tolerate it much better.
